The respo is really the only option if you must have a mask in the UK, anything else will be either too industrial (3M types), or too light weight (painters)
Would suggest checking out how other many riders use them, as I can't remember seen many, if any.
The polution you are going to get will be less than if you were sitting in a sealed up car, and all the trucks and busses there have to be Euro III compliant, so should be pretty clean; just don't sit behind an exhaust!

I have heard that claim a lot, about bicyclists getting less pollution than those inside a car, but have never seen it quantified in a study. I suspect that it is not true, at least with newer cars. Many of those new cars now include filtration of the air, and some even have HEPA filtration of the air coming into the cars.
